Those iran’s waters. These ships are literally passing through their country, I think you’re confused with “territorial waters” as defined in UNCLOS as well but neither Iran nor the US nor pissrael ratified that treaty. Here is a good opinion on why the UNCLOS doesn’t really apply

International customary law applies even if you’re not a treaty member.
International law has no meaning if nations don’t participate.
For example, the United States has laws and policies designed to prevent the arrest of U.S. personnel and its allies by the International Criminal Court (ICC). The 2002 American Service-Members’ Protection Act (ASPA) authorizes the US President to use “all means necessary and appropriate” to release U.S. or allied personnel detained by the ICC, often termed the “Hague Invasion Act”.
** Iran is right about which rules are universal **
I don’t know how much clearer it gets??? Who’s gonna argue that UNCLOS is universal anyway? The US or pissrael? Neither of which are party to the UNCLOS and who very much assert authority outside their territorial waters?
